TYPEWRITING HACHIN E.

Application illed December 11, 1925. Serial No. 74,667.

This invention relates to machines for typing upon fan-fold "webs, and particularly to means for slitting the folds.

It has been the practice to interleave the 6 webs with carbon-sheets, and to attach these carbons to a carrier, for shifting them along after the typing of a form is completed, preparatory to typing upon the next form. It has also been the practice to mount slit- 10 ting knives upon the carbon-carrier, so as to slit the web automatically at the operation of stripping the carbons.

The multiple-ply web is thus caused to consist of loose plies at the intake side of the platen, whereby some of the advantage of fan-folding the lies is lost. To overcome this difiiculty, slltting knives have been arranged between the carbon-carrier and the platen, thereby substantially reducing the length of the split-apart plies at the intake side of the platen, and maintaining the web in whole condition that much longer.

One of the main features of the present invention relates to simple, practical and inexpensive means, readily adapted to existing machine, for slitting the web into separate plies at the delivery side of the platen.

The invention is shown applied to amachine of the type disclosed in the Wernery & Smith Patent, No. 1,132,055fdated March 16, 1915, in which the typewriter platen is elevated to permit the webs to be straightened out, for making it practicable to strip the carbons along the web.

The practice is taken into account of severing the multiple-ply web transversely at the completion of the typing of each form. This severing is usually attended to after the carbons have been shifted to position for typing the next form; and at such a time the leading edge of the web usually stands at a height about level with the top of the platen. This condition presents the problem of presenting the fold-slitting knives within the plies of the web, without interference of the slitting knives with the transverse websevering knife, and without encountering still other difliculties. It is an object of the invention to overcome all these difiiculties no and to avoid the necessity of rethreading the fan-fold web upon the slitting knives preparatory to performing each slitting operation.

- According to the present invention, the

points of the slitting knives always remain between the web-plies. At the conclusion of the operation of slitting any form, said points are caused to project or advance a certain distance between the plies in the succeeding untyped form of the web. This avoids the necessity of rethreading them at every operation; and interference between the slitting knives and the web-severing knife is also avoided; while the folded web remains integral up to about the printing point, and-preferably untilafter the web has passed the printing point, so that the advantages of fan-folded webs are all preserved. To achieve these results, the s'littin knives are mounted at the delivery side 0 the platen. In inserting the web into the machine, the knives are inserted properly between the plies; the latter preferably being preliminarily slit at the leading end of the web, so that they may be spread open for the insertion of the knives. The web-slitters, however, after the introduction of the slittingsknives, as already explained, stand just below the top of the second form, as the first form is positioned by the gage which is provided for gaging the leading end of the web. The first form on the web need not be typed, but may be regarded as waste. The

second of the forms is typed. The knives remain idle in normal positions durin the line-by-line advance of the web whic occurs at the typing of said second form.

The folded side edges of this first Webform may be slit by hand, if desired, before inserting the same into the machine, and the slitting may extend down for some distance into the top portion of the second form to give clearance for the slitting knives herein described; the knives subsequently producing their own clearances, as w' be explained.

When the typing of the second form is complete, and the web is gaged to position for severance and for beginning the typing of the first line on the third form, the slitting knives are pulled downwardly, thereby slitting the folds of said second form. This slitting proceeds down to an excessive extent, bringing the knife points to positions somewhat below the top of the third form, whereby a knife-clearance is out in the tops of the third-form plies. The use of this clearance will presently appear. Still prior to out idle between the plies during the line-byline typing of said third form. By the time that the third form is completed, or nearly so, the knife points will have positions between the plies of the third form, at its upper portion. That is, the points will be be- ,low the second form and within the clearances already mentioned in the top of the third form. The web-severing knife is above the fold-slitting knives, so that when the web is positioned for severance, the slitting knives will be entirely within the third form.

At the completion of the ty ing of said third form, therefore, the lea ing edge of the second form is brought up against the top gage, and the carbons are stripped back to the fourth form. Then the slitting knives are drawn down thus slitting the folds of the third form and forming clearances in the top of the fourth form The knives then return up to normal positions, and the second form is torn off, and the t ing of the fourth form proceeds, the slit thii 'd form remaining in the machine.

The slitting knives may be mounted upon a truck or carrier which is mounted to extend across a slitting and web-severing table at the delivery side of the platen, the table preferably extending upwardly and rearwardly from the platen. This table is swung forwardly and downwardly, togetherwith the platen, preparatory to the carbon-stripping operation. Said stripping blade carrier is mounted for. easy movement-up and down said table, and is normally supported in itsupper position, in which it stands just below or clear of the transverse web-severin knife.

Figure 6 is a front elevation oi the ma chine seen in Figure 2.

Figure 7 is a sectional plan illustrating the truck which carries the slider blades.

Figure 8 is a sectional plan, showing the adjustable web-severing knife and appurtenances.

The fan-fold web 10 is threaded through the usual carbon-carrier 11, the sheets of carbon 12 interleaved'with the plies of work Web. From the carbon-carrier the web runs forwardly and downwardly around a platen 13, as illustrated in said patent to Wernery & Smith. The web is divided into forms, of which the second is being filled up by means oftypes 14 at Figure 2. The first or initial form, whose lower boundary is indicated at 15, does not need'to be typed; but after serving the hereinafter described temporary purpose it ma be torn off and thrown away. The typing 0 the second form proceeds, the platen 13 feeding along with its carriage 16, as set forth in said patent.

Upon the completion of second form, the platen 13 is swung upwardl as at Figure 3, and the leading edge of the first form-is brought up to a gage 1:1, which is adjustable along-- a staff 18, the latter extending up from a slitting and severing table 19, that is erected at the de-' livery side of the platen upon a swinging platen-frame which is mounted upon the carriage 16. Having adjusted the leading edge of the web to the gage 17, the operator detains the web at that point while he pushes back the handle 21 usually .provided upon the carbon-carrier 11, until it is arrested by an adjustable gage 22, -thus strapping the carbons 12 from the second-form, whose bottom boundary is indicated at 23, to the third form, preparatory to typing the latter. Then the platen-isswung down to normal position, theta'ble 19 returning to its rmal upwardly and rearwardly inclined position, as-at Figure 4. At this time the stripped or shifted carbons now stand just above the printing line on the platen, Figure 4. Before typin however, opposite handles 24 are sped and pulled downwardly along the table 19, thereby slitting apart the fanhe typing of the,

45 by the platen arid the usual feed-rolls 39,

fold webs; these handles 24 being provided upon a vertically movable truck 25, Figure 7, overlying the table and extending thereacross, Figure 6. Upon the opposite sidesof the truck are mounted fold-slitting blades c 26, inserted within the folds of the web and pointing forwardly and downwardly, so as to slit the web by a downward movement of the blades toward the platen from the position at Figure 6 to the position at Figure 4. The truck is guided for parallel movement by means of pinions 27 mounted upon the ends of a shaft 28 and meshing with stationary racks 29, mounted on opposite side edges of the table 19; said shaft journaled in brackets 30 depending from the truck 25. The blades are clamped together by thumbnuts 31 at opposite ends of the table, fitted 34 wound about the shaft 28 lifts the truck to normal position against a stop bar 35, which. extendsacross the table and above the same and is adjustablysecured thereto by thumb-screws 36. Said" thumb-screws and bar may work in'the same grooves 37 in the opposite racks'29 that serve as tracks for the slitting-knife truck; and the thumbscrews 36 may be threaded into lugs 38 secured to the ends of said stop bar-and hearing upon the top edges'of the racks.

The slitting operation having been completed, the typing may now proceed line by line until the second form is completely typed, the web being drawn into the machine and feeding up freely along the table 19 past the slitting knives 26, which remain idle in normal position during the typing ofeach form. At the conclusion of the typing of the second form, the knives stand entirely below said form-,and between ;the plies of the third form at the upper portion thereof, being located in the clearances that were produced as described at the conclusion of the slitting operation seen at Figure 4. At this point the platen is again raised, the parts brought to the position at Figure 3, the top of the second form being brought to the gage 17, and the carbons are shifted back to the afourth form, The platen and-its swing frame 40 are returned tonormal positions together with the table, the second form is torn off by knife 41, and the typing ofthe fourth form begins.

to the ends of the racks.

the table maybe supported by a. bracket The web-severing knife-blade 41 moves up and down the table to accommodate forms of different lengths, and the gage 17 may be adjusted accordingly. blade 41 may be secured upon the above-described lugs 38, so that both the stop bar 35 and the knife-blade may be adjusted together up and down the table, thus providing for a regulation of the length of the stroke of the fold-slitter, as well as of the length of the form. The racks 29 extend alongside the table ,19 to form a framework for the table. At the upper ends the racks are joined by a'rigid cross-bar 42, conducing to the stiffness of the entire table structure; the bar being secured at its ends by screws 43 At its lower end 44, which may include a cross-bar 45 and pairs of arms 46 and 47 extending up from the ends thereof and fixed to the table; the arms 47 being secured by screws 48 to the side members of the swinging platenframe 40.

The slitting strokes of the slitting truck The knifemay be limited by stops 49, secured upon the lower endsof the racks 29;

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.
